| Abstract: | Mw7. 5 and Mw9. 0 earthquake occurred near the east coast of Japan in March, 2011. The earthquake and its trigged tsunami caused the huge damage. This research apply the back projection method, which is one of the common method of study the big event, to determine the source character of these two earthquakes. |
